• 10:00 Keynote lecture by Johann Kollegger: Building lightweight concrete structures

Already in the early phases of the conceptual design of lightweight concrete structures the later construction process must be considered. Only by keeping the construction method in mind from the very beginning of the design process an economic and sustainable structure will be obtained. In the lecture construction methods for thin-walled shells and bridges will be explained and some recent applications to real structures will be shown.

• 11:00 Keynote lecture by Oliver Sander: Locking

Finite element simulations of thin structures are plagued by locking, a dreaded phenomenon where structures appear much stiffer than they really are.  The reasons for locking are not obvious, and consequently the typical counter-measures are not quite obvious either. In this talk we will explain how locking happens, and how some of the standard methods to avoid it work.

• 13:00 Presentation of home work by the participants: Graphical work from lines
• 14:00 Introduction to Line Geometry by Kevin Noack, Introduction to GH-plug-in LineGeometry by Daniel Lordick, Examples by Martin Eichenauer

• 10:00 SOFiSTiK-Workshop by Juan Pablo Osman Letelier, Konrad Freymann, and Max Dombrowski using a Rhino plug-in and alternatively a Grasshopper interface

A brief introduction to structural optimization and particularly to form optimization will be given. The focus will be on the structural design of ruled surfaces with practical applications in the fields of architecture and civil engineering. Beginning with the basics of structural analysis, the fundamentals of the structural behavior of shells will be shown through theoretical and practical examples. 

Furthermore, a software module developed at the TU Berlin for the evaluation and optimization of structures will be presented. GHToSOFi provides an interface between the parametric modelling software Grasshopper and the Finite-Element-Software SOFiSTiK.With didactical examples, the generation of parametric models and their exportation into a FE-software for form optimization will be demonstrated.

• 10:00 Keynote by Diana Wehmeier: PLASMA – interplanetary art & science magazine (PLASMA magazine) 

As technology has advanced, so has science fiction, painting more and more realistic portraits of what life in space could look like. Science and Sci-Fi are slowly coming together forming a new reality where the craziest dreams have started to become true. What impact does the life as an interplanetary species have on politics, economy, culture and architecture?

• 10:00 Keynote by Toni Kotnik: Design of Structures – Research into configurational logics

In architecture as well as in engineering, structural design is often viewed as mere problem of stability and efficiency. But structures, understood as relationship between elements, are articulations of order, are patterns of organization with architecture arguably the most prominent manifestation of the basic human activity of structuring the environment we are living in. Structures in architecture, thus, are not only physical but also conceptual. Structures are a medium of expression of design ideas that travers all scales of architecture. Based on such an understanding, the lecture tries to sketch a research into the configurational logic of structures as an interdisciplinary research project with architecture at its core.

Participants will learn to utilize these algorithms in tandem with the structural models defined in Karamba to optimize the geometry of the models.

Smart materials are capable of adapting self-sufficiently to changing environments respectively changing their characteristics specifically to external effects in order to adjust to their surroundings. Thus, they allow high functionality in simplified structures which allows breaking new ground in product design. Instead of hitherto separation of function and structure, Fraunhofer IWU and smart³ aims at integration functionality into the material's structure. In particular, the smart materials contribute to providing light-weight structures with sensors or actuators. These can be used for monitoring or manipulate material properties.

Furthermore he will broach the issue of optimized solver tuning and discuss some details of the software development of FlexHopper.

In lightweight fiber-reinforced composite structures, their intrinsic anisotropy needs to be addressed in order to fully take advantage their ability to withstand loading with lower safety factors. Stress adaptive curvilinear fibers following pre-calculated paths, lead to significantly increased strength- and stiffness-to-weight ratios when compared, for instance, to classical multiaxial composite laminate. For the production of curvilinear fiber patterns, the Tailored Fiber Placement (TFP) technology was developed at the IPF Dresden. Since TFP is a technology with many degrees of freedom, generating optimized fiber layouts is particularly challenging. Within the lecture the state of the art in extreme lightweight design based on a variable-axial fiber architecture will be presented and current modelling approached will be explained. Afterwards several composite sample parts as well as latest development in fibrous concrete reinforcements will be shown within a lab tour.

Within the development of competitive high-tech products a profound rethinking from classical materials, designs and technologies towards multi-material design and adapted manufacture processes becomes apparent. Thus it is possible to significantly extend the field of application of materials in technical systems with regard to a sustainable and energy efficient future, particularly in traffic engineering as well as in machine building and plant engineering. Especially for extremely stressed lightweight structures constantly rising demands increasingly require the use of new materials with advanced property profiles. Due to their selectively adaptable characteristics, endless fibre reinforced composite materials are clearly superior to conventional monolithic materials. Advanced textile technologies and processing methods offer the highest flexibility for the adaptation of the property profile with regard to complex loading conditions. They can purposefully be designed by novel cross-scale simulation methods and technologically implemented by advanced manufacture processes.

• 16:00 Keynote by Mike Schlaich: Do double-curved shell bridges make sense, or should a bridge not rather be a linear structure?

Usually bridges are considered as two-dimensional structures which are just wide enough to accommodate live loads and to provide sufficient stiffness for transverse loads such as wind and earthquake. There are cases, however, where parts of the bridge or the entire load bearing structure are (double)-curved in order to carry loads very efficiently via membrane forces, i.e., compression or tension only. A selection of bridges that qualify in this sense as shell bridges will be shown and described.
Then a shell that forms both structure and deck, the stainless-steel footbridge in Ditzingen, Germany, will be introduced. The double-curved shell spans 28m with a plate thickness of only 20mm. Laser cut holes in the shell not only make the structure lighter and translucent, but also the remaining steel work visualizes the path of the principal membrane forces, thus making the bridge more understandable.
Shell bridges stimulate the senses and they promise the advantages of shells, namely minimized weight, elegance and stability.
